No one told me either, until today as well. :)
Memories are time stamped and are spatially organised.
Who Discovered time cells?
Lega and his team found the time cells by studying the brains of 27 people who were awaiting surgery for severe epilepsy. 29 Oct 2020
the team Gray Umbach, Pranish Kantak, Joshua Jacobs, Michael Kahana, Brad E. Pfeiffer , Michael Sperling , and Bradley Lega

Time cells are neurons in the hippocampus and entorhinal cortex that fire at specific moments within a cognitive task or experience.
you mean neurons could fire in sequence, and a sequence of neutral firing could relate to sequential tasks or experiences

Well there’s a few people I know that don’t have any of those. Wouldn’t have a bloody clue what day it was.

What the researchers think is people with epilepsy may not be time stamping their memories properly, they recall them in any order where people with no epilepsy are time stamping memories in the correct order.

sure though that probably occurs in people without epilepsy too

Yeah, but I would guess that a different mechanism is involved between the two groups.

but the simplicity or parsimonious principle would suggest that a similar mechanism would be more likely

Imagine bringing in all that external sensory information, the outside world, all that information about the outside world flows into your body, you see it, hear it, feel it, smell it, taste it, your body is sensing all this all the time 24 ×7 it doesn’t turn off, well, it flows into your body and in the hippocampus, all that jumbled sensory information gets time stamped, placed stamped, somehow these memories are then organised (filtered), and stored in the brain for later recalling.
Time cells are neurons in the hippocampus and entorhinal cortex that fire at specific moments within a cognitive task or experience. While many prominent theories of memory encoding offer time cells as the source of the temporal component to memory, they have never been observed in human recordings.
A place cell is a kind of pyramidal neuron in the hippocampus that becomes active when an animal enters a particular place in its environment, which is known as the place field. Place cells are thought to act collectively as a cognitive representation of a specific location in space, known as a cognitive map.

Maybe. Further research will iron out differences.

Interesting work, my question would be after everything is time and placed stamped, where does the brain decide “where” to store the memories in the brain?
Is reading a scene about walking in the bush stored somewhere different to say a memory about actually walking somewhere in the bush.
Are abstract thoughts stored differently to thoughts about being somewhere in space time.

Thanks!
I’ve been wondering for ages how my brain manages to encode the entire 16 minutes of “Eine KIeine Nachtmusik” without doubling up or tripping over itself.

Certainly took their time telling you that’s for sure, they could have said something, just being there…so to speak.
